Step 1: Drilling and Connections
Open your Cabinet cover.
Take apart your FDD closure, make a hole with your drill machine of 12mm. Here I made a hole with my solder iron
Attach the Key operated switch with the wire hanging inside the CPU.
Put back the FDD closure.
As this closure is replaceable I drilled it here instead the whole cabinet
Find the figures
Step 2: Making Connections
Connect one of your terminal CPU switch to one terminal of Key switch via a small jumper wire
Use your soldering techniques
Step 3: Connecting to Motherboard
Find the exact PowerSW terminal in the Motherboard and connect the rest two terminals to that corresponding MBD SW
Step 4: BIOS Confiure to Keep in Stay OFF Mode
